Filesystem directories entries hold more than file and directory
objects. As well as symbolic links, there's named FIFOs, named sockets,
and devices.

E.g.

$ mkfifo a-fifo
$ nc -lkU a-socket&
$ ln -T target -s a-link

$ ls -l a-*
prw-r--r-- 1 tixy tixy 0 Jan 17 12:07 a-fifo
lrwxrwxrwx 1 tixy tixy 6 Jan 17 12:08 a-link -> target
srwxr-xr-x 1 tixy tixy 0 Jan 17 12:07 a-socket
